To find the old threads you have to use the search correctly, at the top right hand corner of the page there is the white search box, inside the box type "gold gun" you must use the quotes
or it finds every thread that has the single word GOLD or GUN in it, your search result should give 23 threads.

There's still these LRL articles on Geotech1 :

The Gold Gun was not an LRL in the traditional sense of an outright scam. I believe it's a directional AM receiver which could be used to locate conductive ore bodies. However, the way it was marketed was highly deceptive.

is this the one

Whats the theory of using a AM receiver ?, does the received signal increase when you walk over the ore body ?

received signal from what TX source?

Something like that. Or it may be a decrease, I don't recall.

I remember an article in a popular electronics from the early 70's with an article on using an AM radio but from what I remember they were sending the signal into the ground through ground rods.

AM broadcast radio station.

AM broadcast radio station.

9-27kHz range is AM?

I have no information on how this device is supposed to work I am only guessing they tune it to a AM station or some other radio signal that's available.

The AM Broadcast band in the USA is 530 kHz to 1700 kHz.

From Wikipedia:
"Medium wave (also known as Medium frequency (MF)), which is by far the most commonly used AM broadcasting band. In ITU Regions 1 and 3, transmitting frequencies run from 531 kHz to 1602 kHz, with 9 kHz spacing (526.5 kHz - 1606.5 kHz), and in ITU Region 2 (the Americas), transmitting frequencies are 530 kHz to 1700 kHz, using 10 kHz spacing (525 kHz - 1705 kHz), including the ITU Extended AM broadcast band, authorized in Region 2, between 1605 kHz and 1705 kHz, previously used for police radio."

we must search the description on this detector. or full info. i see those frequencies maybe specific choised for every country.
naked sch does not give clear picture.
